Question

我正在尝试将BETWEEN用于日期，但它仍然失败，因为它只返回所有结果，如果我做=或者它工作正常但是没有人可以帮助，谢谢

WHERE CASE 
    WHEN [BVContact] IS NOT NULL
        THEN convert(VARCHAR(10), [ContactStarted], 103)
    WHEN [TelephoneConsultationStartedBy] IS NOT NULL
        THEN convert(VARCHAR(10), [TelephoneConsultationStarted], 103)
    WHEN [HomeVisitContactBy] IS NOT NULL
        THEN convert(VARCHAR(10), [HomeVisitContactStarted], 103)
    ELSE ''
    END between '01/10/2016'
    AND '02/10/2016'

Answer 1

    WHERE CASE 
    WHEN [BVContact] IS NOT NULL
        THEN convert(VARCHAR(10), [ContactStarted], 120)
    WHEN [TelephoneConsultationStartedBy] IS NOT NULL
        THEN convert(VARCHAR(10), [TelephoneConsultationStarted], 120)
    WHEN [HomeVisitContactBy] IS NOT NULL
        THEN convert(VARCHAR(10), [HomeVisitContactStarted], 120)
    ELSE ''
    END between '2016-10-01'
    AND '2016-10-02'

其中convert（varchar（10）表示日期之间不起作用
